To all whom it may concern.-

A Be it known that I, FREDERICK INGER- soLL, a citizen of the United States of America, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Amusement Devices, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in amusement devices; and the invention relates more particularly to that type of amusement apparatus commonly known as a "circleswing, roundabout, or merry-go-round.

The invention has for its primary object to provide an apparatus of the type stated above wherein a plurality of carriages or chariots are suspended to be operated and caused to move or swing in a circular or curvilinear path, whereby persons occupying the carriages or chariots may experience sensation similar somewhat to that of flying through space.

The invention has for its further object to provide a strong, durable, and e ually-balanced apparatus particularly adapted for amusement-parks and like places.

The invention in its broadest aspect involves positive and reliable means for operating a circle-swing, as it will be hereinafter termed, in an undulatory manner while the apparatus is in motion. To this end I have devised an apparatus embodying a plurality of structural elements which when combined produce a safe and comparatively inexpensive apparatus.

The principal elements of the invention namely, a base and pedestal, a non-frictional equally-balanced bearing-frame, revoluble supportingframes, supporting-Outriggers, a dome, and carriages or chariots suspended from said domewill be hereinafter separately and specifically described in detail, together with the novel arrangement and objects accomplished from such a combination of elements.

The preferred embodiments of my invention are illustrated in the drawings accom panying this application; but I desire it to be understood that the same are susceptible to various changes without departing from the scope of the invention.

Reference now being had to the drawings accompanying this application, like numerals of reference designate corresponding parts throughout the several views, in which Figure l is a diagrammatic side elevation of my improved apparatus.

sembled in their working re ations.

The circle swing or apparatus in its entirety is constructed of strong and durable metal, consisting of castings, angle-bars, and

tubular frames or braces, which are assem-; bled to dprov-id e a rigid non-frictional equibalance frame, from which a plurality of cars, carriages, or chariots may be suspended. When the ap, the frame is revo' ved, the centrifugal force exerted by the revolvin frame is adapted to the carriages or c ariots outwardly to travel "in a circular path, from which they may be deviated by reducing the speed at which the apparatus is operated to cause them to travel in a curvilinear path. Throughout the entire construction of the apparatus I haveaimed to produce a safea. paratus which can be operated in an undu atory manner,

. whereby the structure will not be subjected are braced by radially-disposedvertical ribs to strains or stresses when in operation.

Considering the various elements of the invention in detail, reference will first be had to the base and pedestal of the apparatus.

Base and pedes:'taZ.The base 1 and a portion of the pedestal or tower 2 is made of a casting and consists of a hollow frusto -conical-shaped pedestal having a flared annular base. The annular base 1 and the pedestal 2 3, which extend from the base 1 upwardly within the pedestal 2. The outer edges of the base are recessed, as at 4 and pierced, :as at 5,, order that the base may be firmlyan- Fig. I

Fi 49 is a horizotal secaratus is in operation and 1 Basis chored to a suitable foundation. The base is also provided with an annular shouldered recess 6, upon which is adapted to rest a bearing-ring 7, forming part of the bearingframe to be presently described. The upper end of the pedestal 2 is provided with an annular pierced flange 8, to which is secured a supp'lemetary pedestal or tower 9, having inner bracing-ribs 10 similar to the lower portion of the pedestal.

' Upon the upper end of the supplementary pedestal or tower 9 is revolubly mounted a cap 11. (See Figs. 43, 44,and 54.) The cap consists of a sleeve 12, havinga central spiderframe, 14, which supports a collar 15. The

lower end of the sleeve 12 is provided with sets of apertures 16, while the upper end of the sleeve above the spider-frame 14 is flared inwardly and provided with pierced bosses 17. The object of said bosses, together with the apertures 16, will presently ap ear. Bearingframe.surrounding tlie pedestal 2 and supported by the base 1 is a non-frictional equibalanced bearing-frame, said frame comprising an annulus or ring 18, having an inner vertically-disposed pierced flange 1 9. (See' Figs. 11, 12, 13, and 54.4) The outer edges of the annulus or ring 18 are formed with a circular rack 20, and between the flange 1 9 and said rack the annulus or ring is provided with depending bearings 21., which aredisposed radially to the aXis-ofsaid annulus or ring. Circumferentially:arranged relative to the annulus or ring 18 and at each side of the bearings 21 are segment-shaped depending collars 22., the openings in said collars being formed upon an are having for its center the aXis of the bearings 21, i n-co.n nection with which said collars are used. The annulus or ring 18 is formed with an inwardly-extending flange 23, the bottom side of which forms a seat 24 'f0r a bearing-ring 25, (see Figs. 10 31, and54,) said ring 25 having -a beveled bearing-face 26.

The bearing-ring 7, mounted upon the base 1, (see Figs. 30, 54,) is provided with a beveled bearing-surface 27, (see Fig. 30,) upon which is mounted a plurality of revoluble cone-shaped rollers or bearings 28. The roll ers or bearings 28 are journaled upon pins29,

-mounted in radially-disposed bosses 30, car

ried by a guide-frame 31. (See Fig. 21

The cone-shaped rollers or bearings 28 are cured together by bolts 37, (see Fig. 15%,)

which pass through the ends of the housing 33 and cap and extend upwardly through the collars 22 22 upon each side of the opening in which the bearing-housing is mounted, said bolts supporting the bearing-housings, at the same time guiding them in their movement. Journaled within each bearing is an upwardlyextending pin 38, which is provided with an annular shoulder 39 .in order that the pin may be retained within the housing. Upon each pin is keyed or otherwise mounted a roller 40, adapted to engage the periphery of the bearing-ring 7. As the bearing-frame, particularly the annulus or ring 18, is revolved the rollers 40 are adapted to engage the periphery of the bearing-ring 7 and together with the cone-shaped rollers 28 perfectly balance the ring or annulus 18 upon the base of the apparatus. The bearinghousings 32 are arranged at a slight angle, whereby they will conform to the periphery of the bearing-ring 7, also permitting of a slight adjustment through the medium of the segment-shaped collars 22 and the bolts 37, which permit of the bearing-housing partially rotating relative to the ring or annulus 18. The rollers 40 are adapted to maintain the annulus or ring 18 in proper position upon the cone-shaped rollers 28 and. are adapted to equalize strains and stresses upon the bearing-frame which may tend to shift the annulus or ring 18 relative to the coneshaped rollers 28. The inwardly-tapering rollers 28, together with the bearing-rings7 and 25, are also adapted to equalize the strains and stresses that may be exerted upon the revoluble bearing-frame and in-conjunction with the rollers 40 insure a perfect equilibrium of the entire apparatus.

R evoluble supporting-frames.The frames, of which there are six in number, or may be more according to the size of the apparatus, are secured to the cap 11 of the supplementary pedestal or tower 9 and to the flange 19 of the ring or annulus 18. Each frame is substantially triangular in outline (see Figs. 24, 25) and consists of an angularlydisposed strut 41, carrying a casting 42 upon its upper end and a casting 43 upon its lower end. The casting 42 (see Figs. 33 and 34) comprises a pierced plate 44, which is secured to the sleeve 12 of the cap 11 by bolts or rivets engaging in the sets of apertures 16, afore referred to. The integral web portion 45 of the casting 42 has attached thereto the upper end of an inclined brace 46, which is secured at itslower end, as at 47, to .an outwardly-extending arm. 48, the rear end of which arm is secured by a plate 49 to the strut 41 of the frame. The extreme outer end of the arm 48 is provided with a casting 50, which is secured, as at 51, to the upper end of an inclined strut-brace 52, said brace at its lower end being attached to the casting 43. The strut-brace 52 and the brace 46 are frame. The casting 43 is secured to the pierced flange 19 of the ring or annulus 18 by bolts or rivets 54, as clearly illustrated in Fig. 10 of the drawings.

The castings 50, which are of a peculiar formation, are constructed whereby the main skeleton frame, particularly the Outriggers thereof, may be fastened thereto to form a rigid str'ucture. Each casting consists of a sleeve 55, adapted to receive the outriggers 56 of the main skeleton frame. The sleeve of each casting carries outwardly-extending lugs 57 57, having angularly-disposed openings 58 58 formed therein, adapted to receive the ends of spacingbars, (not shown,) whereby the supporting -frames can be equally spaced aroundthe pedestal or tower of the apparatus. The top of the sleeve 55 is provided with a semicircular flange 60, having openings 61 61 formed therein to receive the ends of tie-rods 62 62.

Supporti'ng-outriggera-The main skeleton framework of the apparatus (see Fig. 1) is balloonshaped, and consists ofa central standard 63, which is surrounded by a plurality of Outriggers 56, said Outriggers being supported from the central standard 63 and from the supporting-frames just described of the pedestal. Each outrigger consists of a plurality of tubular rods 64, which are connected together by couplings 65, said couplings being connected together by spacing-bars 66 and tie-rods 67 67. The spacing-bars 66 form a framework which is hexagon shape in cross-section, and these bars serve to brace and maintain the main skeleton framework of the apparatus. Each one of the couplings (see Figs. 35 to 38) consists of a hexagonshaped body portion 68, carrying diametrically opposed tapering shanks 69 69, having heads 70 70 upon their outer ends of a diame ter equivalent to the base of the shanks 69. The shanks 69 are adapted to extend'into the tubular rods 64 comprising the Outriggers and are secured therein by pins or bolts passing through openings 71 formed in theshanks 69 of each coupling. The body portion 68 of each coupling is provided with diametricallydisposed sleeves 72, in which are secured the ends of the brace-bars 66.- The angularlydisposed edges 73 of the couplings are provided with openings 74 to receive the tie-rods 67 67 of the main skeleton framework. The angularly-disposed face 75 of each coupling is provided with an opening 76 to receive the ends of the converging rods 77, that are se-' cured to a central coupling 78, (see Fig. 40,) carried by the central standard 63 of the apparatus, this standard comprising a plurality of tubular sections 79, which are connected together by couplings 78, (see Fig. 39,) similar in construction to the couplings 75. The lowermost section of the central standard-is secured in or upon the sleeve 15 of the cap 11.

ITO

The lowermost set of couplings are connected by tie-rods to the cap 11 of the supplementary pedestal :9, the ends of the tierods entering the openings formed in the bosses 17 of said cap.

B0me.'lhe uppermost set of outriggercouplings supports a dome 81, which forms the top of the apparatus. The dome is constructed of light angle-iron and is substantially semispherical in contour to give the main skeleton frame a finished and attractive appearance. The are shaped angleirons 82 are secured to the uppermost c0up lings by tie-belts 83 83, (see Fig. 32,) the uppermostitie-bolrt being braced by a sleeve '84, interposed between the angle-irons 82 and ;a section of tubing 85, whic'hextendsoutwardly from the dome and terms a continuation of the outriggers 56. The outer ends of the sections of tubing 85 :are provided with spherical bodies 86, said bodies being formed of light metallic peripheral strips '87, having their ends secured to top and bottom plates 88 88 The peripheral strips 86 are braced by a circular strip or band '89, which is secured to the peripheral strips 87, as at 90. The spherical bodies 8 6 are employed simply as ornaments to give the apparatus a neat and attractive appearance, these bodies also being used for decorative purposes when it is desired to illuminate the entire apparatus by strong and powerful lights that may be conveniently located within the spherical bodies S6.

The arc-shaped angle-irons 82 forming the dome, are secured to :a common plate 91, -secured upon the upper end pf the central standard 63. The ang1e-irons are braced by angile bars .92, the ends -of said bars being cut and sheared to connect the angle-irons 82, as Z cooperation of the movable parts-of the appaindicated at 93 93. (See Fig. "52.)

Centrally upon the top of the dome is mounted a large spherical body 94, comprising a plurality of peripheral ribs ":95 95 and transverse bands or rings 96, which connect the ribs together. The lower ends of the ribs '95 are connected to plates 97., secured to the upper ends of the arc-shaped angle-irons 1 departing from the spirit and scope of the in- 82 of the dome. v

The dome is substantially semispherical in shape, While the Outriggers are arranged in substantially cono-idal formthat is, they are arranged around the central standard circumferentially and inclined outward from said standard. The skeleton conoidallike structure for-med by the "Outriggers, together with the skeleton doame, forms a substantially ball-oon lilae structure constituting the carriage-c-arrying structure.

Generally I prefer to make the outriggers of a sufficient length so that the upper ends thereof will project some distance beyond the lower edge 01' base of the dome in order that objects, as 86, may be mounted on the free upper ends of the Outriggers to add to the I seds general appearance of the structure and to facilitate obtaining desired effects, which, it

will be readily perceived, may be had by electric lighting, etc.

-Uarriages 01' chari0t-s.F=rom the uppermost couplings 65 of the apparatus are sus: pended cars, carriages, or chariots 98, cables 99 being used for this purpose. The car= riages or chariots are adapted to -accomrnodate a number of persons, and the cables99 are arranged whereby the carriages or chariots will be supported in a horizontal plane when the apparatus is not being operated.

I do not care to confine myself to the type of carriage or chariot used her to the manner in which they may be suspended from the couplings carried by the Outriggers of the apparatus.

Operati0n.-1n Figs. 14 and 15 ofthe drawings I have illustrated a pinion or gear-wheel 100,.which is adapted to mesh with the circular rack 2(3), formed in the annulus or ring 18. The pinion or gear-wheel 100 may be re volved by a motor or driven from a suitable source of energy, such as an engine, and when revolved the pinion or gear-wheel is adapted to revolve the annulus or ring 18', carrying the supportingfrarne and Outriggers, and thus impart a rotary movement to the car: riagesor chariots suspended from the frame. In operation the carriages or chariots are adapted to swing outwardly and upwardly I by centrifugal force.

From the foregoingit will be observed that I have devised an equally-balanced structural framework from which a plurality of carriages or chariots may be suspended with perfect safety, and through the medium of the bearings used in connection with the apparatus I obtain practically a non-frictional ratus.

I do not care to confine myself to the numriages or chariots used inconnection with the apparatus, and such changes in the minor details of construction as are permissible by the appended claims may be resorted to without each outrigger consisting of a plurality of tubular rods, couplings connecting said rods together, horizontal brace-bars connecting ber of supporting-frames, Outriggers, car

said couplings, angularly-disposed tie-rods connecting said couplings together, a dome carried by said outriggers, and a plurality of carriages or chariots suspended from some of said cou lings, substantially as described.
